Abstract :

Regarding to increased use of groundwater resources, it seems necessary to have more accurate knowledge of characteristics of aquifers in order to improved usage and accurate management of these resources. In this study, we simulated groundwater flow of Qazvin aquifer usingVisual MODFLOW model, collecting data and statistics, as well as using different studies. The simulation model has operated and it has calibrated through changing the input parameters in logical range and comparing the results to level of the groundwater in observation wells. calibratedmodel has been administered in one year and then it got to validate. We planned different scenarios which is possible to occur in future. Then we predicted the reaction of aquifer to these environmental stresses by implementing the model and they have considered by hydrographicframe of average groundwater level for each scenario separately and the results compared to each other. At end, the results of annual water table balance of aquifer are studied and explained.
